SK3X12V | Triple 12" Ported Universal Fit Subwoofer Box

MSRP: $ 349.99

  • Skar Audio introduces its SK series of line-up of high-performance subwoofer enclosures to bridge the gap between competition-grade quality and universal fit pre-fabricated enclosures.

    The SK3X12V is a triple 12-inch, universal fit, ported subwoofer enclosure. Featuring three independent subwoofer chambers, we engineered this enclosure to produce incredibly accurate and responsive low-end frequency response. In addition, each chamber features its own slot port alongside the bottom of the enclosure, which is tuned for the optimal compatibility and performance of most 12" drivers.

    Quick Facts
    Total Gross Air Space (Volume) 5.50 ft3
    Tuning Frequency 36 Hz
    Cut-Out Diameter 11.125"
    Mounting Depth 7.50"

    When setting out to offer a line-up of premium, universal fit, subwoofer boxes, the end goal was to deliver a final product that was unlike anything else available on the market; setting new standards for quality and performance. That being said, all of our enclosures are hand built using only the finest materials. On top of its outstanding craftsmanship, this enclosure is also braced for extreme strength, and can handle even the most brutally powerful subwoofers.

    Internally, we line several walls of the enclosure with poly-fill to enhance the overall versatility and depth of sound that this enclosure reproduces with any given subwoofer. Each subwoofer chamber also features independent terminal cups, which come pre-soldered and wired internally with 16 gauge speaker leads that allow for an easy subwoofer installation. Finally, the enclosure is finished in a premium black trunk liner carpet and features an embroidered Skar Audio logo on the top surface.

Good box for the price

The box is a good well made box but it doesn't have as low of bass that the 2 12s SDR box did. The box was a little weird to wire because each speaker is in its own chamber but it sounds great and works great. I believe because of the 3 12s that it's louder than 2 15s

Well built box

I am using this triple 12 sub box for 3 JL Audio 123V3 4.
They are wired at 2.7 ohms and sound great in my 2018 Cadillac XTS. The box fit great but is a pain to get in the truck. You have to angle it in. I also drilled a 4 inch hole into both internal walls because the cubic air space is smaller on the outsides then the center sub. The hole is joining cabins making all 3 subs share the same space evenly.

The box came a day early which is always a plus. I love the carpet and Skar Audio stitching on the top. It sounds great and fits perfectly in my Armada.
